“My hair is on fire, I’m really upset about this,” said Missouri Sen. Claire McCaskill, the top Democrat on the Senate Homeland Security Committee.

Roughly one million people come into the United States each day according to Kelly.

“These searches, which affect fewer than one-hundredth of one percent of international travelers, have contributed to national security investigations, arrests for child pornography and evidence of human trafficking,” John Wagner, Deputy Executive Assistant Commissioner, Office of Field Operations, of U.S Customs and Border Protection, said.

“It’s not new, I think it’s being somewhat blown out of proportion,” said Sen. Ron Johnson (R-Wis.), Chairman of the Senate Homeland Security Committee.

The Fourth Amendment protects individuals unreasonable search and seizures by the government. In 2014, the Supreme Court unanimously ruled that police cannot search digital devices, like cell phones, without a warrant. But at the border or port of entry, the Fourth Amendment does not apply.

A bipartisan group of lawmakers wants to change the rule to protect U.S. citizens’ privacy.

Republican Senator Rand Paul is co-sponsoring a bill that will require U.S. officials to get a warrant for border searches.

“I think that's obscene that as an American citizen, myself, you, anybody else who travels abroad and you can’t come back in your own country unless you give up your cellphone and all of its contents,” said Sen. Rand Paul (R-KY).

“There's a big difference between searching your physical items on you when you're crossing the border that could be dangerous, instead of searching a smartphone, or other similar device that may essentially consists of all the info about you,” said Jeramie Scott, Electronic Privacy Information Center.
